Description

Technical Field

[0001] The utility model relates to the technical field of chargers, in particular to a mobile charger. Background Art

[0002] When charging an existing electric vehicle, the electric vehicle needs to be parked at a charging station for charging. However, when the electric vehicle needs to be charged while driving and cannot drive to the nearest charging station, the electric vehicle cannot continue to move, which will cause great inconvenience to the normal use of the electric vehicle. Therefore, a mobile electric vehicle charger is needed.

[0003] Existing mobile chargers are equipped with wheels at the bottom of the charger for easy mobility. However, the weight of the charger itself is relatively large. Once an obstacle is encountered during the process of moving the charger and an emergency stop is required, it cannot stop quickly. The Chinese patent document "CN221233555U" discloses a "mobile charging pile". This solution touches the first transmission rod with the foot so that the first transmission rod contacts the two second transmission rods respectively, so that the second transmission rod can push the T-shaped brake part to move and abut against the walking wheel, thereby realizing the emergency braking function of the charging pile. However, when a person pushes the charger to move and encounters an emergency and needs to stop urgently, he needs to lower his head to find the position of the first transmission rod, and then touch the first transmission rod with his foot. This process will consume extra time, so that the charger cannot stop moving in time. Utility Model Content
